These numbers indicate the diameter of the can end. The most common sizes are 200 (typically used for slim cans) and 202 (common for standard and sleek cans).

LOE (Large Opening End): Designed for easy drinking and pouring. Offers a larger opening than standard can ends, enhancing the consumer experience, particularly for aromatic beverages.

‍SOE (Standard Opening End): This is the traditional opening size for beverage cans. It's designed for optimal sealing and convenience, maintaining the familiar can opening experience.

‍FA (Full Aperture): Full Aperture ends allow the entire top of the can to be removed, turning the can into a cup-like container. This design is ideal for products where a wide opening is beneficial, like certain craft beers or ready-to-eat foods.

Embossed or incised markings on can ends comply with local regulations or serve promotional purposes. In Canada, they typically indicate "RECYCLABLE" or "RETURN FOR REFUND". In the United States, these can be in the form of 4-state, 6-state, or 10-state markings, or other designs, depending on local laws.

SOT (Stay On Tab): This is the most common type of can end in North America, where the opening tab stays attached to the can after opening.

‍RPT (Ring Pull Tab): This design features a ring that is pulled to open the can. It's more common in certain countries in Asia and Europe.

B64: This is a traditional can end type, known for its compatibility with various filling and sealing machinery. It's widely used due to its reliability and standard design.

‍CDL (Countersink Double Seam Lid): A more modern and lightweight can end. It features a smaller diameter for material efficiency and is compatible with specific canning lines. CDL is distinguished by its advanced sealing capabilities, making it suitable for beverages requiring extended shelf life.

The internal coating protects against corrosion and product interaction. Common types include:

‍Epoxy Coatings: These are traditional coatings known for their excellent adhesion and durability. They provide strong resistance to corrosion and are widely used in food and beverage cans.

‍BPA-NI (BPA Non-Intent) Coatings: BPA-free alternatives, offering similar protection while addressing health concerns.

Both epoxy and BPA-NI coatings play a crucial role in maintaining the quality and safety of canned products, but the choice between them can depend on regulatory requirements, consumer preferences, and specific product needs.
